Trial Outcomes & Findings for A Research Study to Characterize the Pharmacodynamics and Safety of Repeat Dose SP-102 (NCT NCT03613662)
NCT ID: NCT03613662
Last Updated: 2022-01-13
Results Overview
Dexamethasone-induced hypothalamic-pituitary-adrenal (HPA) suppression is evaluated by monitoring SP-102 induced changes in plasma cortisol levels from Baseline. The T1 (index) and T2 (repeat) injections of SP-102 are separated by 4-8 weeks

SECONDARY outcome
Timeframe: 12 weeksPopulation: 19 subjects were enrolled and received an index (T1) injection of SP-102. 15 subjects received a (T2) injection of SP-102. Data was not recorded for all subjects at each time point.
The NPRS is an 11-point scale (0- to 10-point scale where 0 is no pain and 10 is worst pain imaginable) that allows subjects to rate the severity of their pain intensity at various points in time (Turk et al., 2003). Subjects used the NPRS to record their current pain, average pain over 24 hours, and worst pain over 24 hours for both affected leg(s) and back pain. NPRS average leg pain scores over 24 hours are presented.
